Toray Plastics has introduced new TreaTear LT Series of linear-tear, polyproypylene sealant films for consumer packaging goods and converters.
The new sealant films offer low seal initiation temperature (SIT) and high heat-seal strength, thereby becoming ideal for all types of non-retort pouch lamination, including stand-up pouches that require a low SIT.
Toray Plastics Torayfan division sales senior director Chris Voght said: "The demand for pouches, especially stand-up varieties, grows daily.
"A versatile, thin film with excellent sealant properties and precise tear is an important development for pouch manufacturing, usability, and consumer satisfaction."
The TreaTear LT films are made using Toray's proprietary design, which delivers a precise machine-direction linear tear, eliminating the need for laser scoring, perforations, or registration, the company said.
These films with a thickness of around 30 microns offer yield advantages over traditional 60 or 70 micron sealant films.
Manufacturers can use TreaTear LT films in place of traditional nylon directional-tear film due to their flexibility with overall lamination design.
Available in clear, white, and custom colors, the TreaTear LT Series is compatible with most zipper stocks, as well as FDA- and CONEG-compliant.
Currently, Toray Plastics manufactures polyester, polypropylene, bio-based, and metallized films for flexible and rigid packaging, lidding, graphic, industrial, optical, and electronic applications.
The company also manufactures polyolefin, polypropylene, and polyethylene foams for the automotive and flooring industries.
In March this year, Toray Plastics developed PWX5, a metallized Biaxially Oriented Polypropylene (BOPP) film that can be used as a high-performance inner moisture and oxygen-barrier web in gas-flushed applications.
